Technical Accountant

About the role

This is a senior individual contributor role and the Controllership team's primary technical accounting expert. You will own the most complex and judgement-intensive accounting areas across the Group - spanning the UK insurance broker, claims handling, car finance and its associated SPV structure, and the Group holding company - and act as the go-to resource for the team, business stakeholders, and external auditors on technical accounting matters. You will work with a high degree of autonomy, reporting directly to the Group Financial Controller. You are expected to solve complex problems independently, document and defend accounting positions to audit standard, coach more junior colleagues, and communicate clearly to senior stakeholders across Finance and the wider business. This role sits at the heart of the Group's effort to close legacy accounting gaps, maintain audit readiness, and build controls that scale as Marshmallow grows. London (hybrid, 3 days in office)

Additional Information

We're on a mission to make migration easy. We started building Marshmallow in 2017. Since then, we've grown from 3 to 700+ people, gained unicorn status, raised ~£140M over three funding rounds, turned profitable, insured millions of drivers and lent millions in car loans. But we're only just getting started. Our goal is to become one of the largest financial services providers in the world. Over the next 10 years we'll grow exponentially, not only by scaling our existing products, but also by building new ones. To achieve our goals we need incredibly ambitious, commercially driven people who never settle for 'good enough'. Marshmallowers are hungry for autonomy and ownership, and would rather improve than coast. Everyone raises standards and has an impact, with a focus on collective success over self-interest. We've created an environment where curious, tenacious people win and grow together. If that sounds motivating, this could be the place for you.
